FIELD: textile industry. ^ SUBSTANCE: invention relates to chemical technology of fibrous materials, in particular to dyeing processes and finishing. Method of combined dyeing of cotton textiles with crease-resist formaldehyde-free processing comprises impregnating fabric with dyeing solution containing dye and organic polyatomic acid or aromatic series acid selected from group including benzoic, salicylic, and acetylsalicylic acid followed by heat treatment for 10 min at 130°C and rinsing. Advantageously, impregnation is carried out with dyeing solution further containing Na2P2O7 or Na3PO4 or MgCl2 at acid-to-catalyst weight ratio 1:1. ^ EFFECT: improved dyeability and crease resistance of cotton fabrics with up to two times improved resistance to mould. ^ 2 cl, 4 ex |
